Gentlemen,
Google’s design premise is to keep it simple and smart, i.e. do what the user probably wants without asking them. A lot of modern software does this. In Google’s case, they use your IP, your language settings in the browser, your Google account (if you are logged in), cookies with info from earlier visits…
much information which effectively means, that you can’t precisely control anymore, which version of the many, many Google-homepages you get. Given you that choice would require a complicated user-interface after all and in certain circumstances isn’t even desired by Google. Users from China, for example, will always get a censored Google, no matter which top-level domain they choose, no matter their language settings or Google accounts.
Even if we suppose (reasonably) that Google is not evil, this hidden set of conditions illustrates a new kind of emergent behavior which we have to get used to with computers becoming ever more complex, subtle, smart and possess more information.

It is not necessary to assume computers will some day develop evil intentions to take over the world. Even with the best of intentions, they can drive us crazy already. And transform joy of use into despair.
